Maintenance Checklist for Metal Roofing on Commercial Buildings

Superb insulation and energy efficiency are the main reasons many business owners choose metal roofing for commercial buildings. It is more durable and lasts longer compared to other roofing materials so it needs less frequent replacement. But that doesn’t mean it does not need any maintenance. 

Even high-quality metal roofs can develop rust, leaks or loose panels if it isn’t properly maintained. A routine maintenance schedule helps pick up on problems early, reduces the repair costs, and extends the life of your roof. Now that we know the importance of roof maintenance, read the blog below to learn about commercial metal roofing system care checklists.

Commercial Metal Roof Maintenance Checklist

Schedule Regular Roof Inspections

Metal roofing should be inspected twice a year, generally in spring and fall. Seasonal inspections give you the opportunity to gauge how weather is affecting your roof and prepare it for coming extremes.

Besides inspecting the roof after a storm, you should also follow your eyes in the aftermath of big storms with heavy winds or hail. Look for loose panels, rust spots, standing water or damaged flashing. Routine inspections catch small problems early, before they turn into expensive repairs. In extreme cases, commercial metal roof replacement might also be required.

Clean the Roof Surface

Keeping your roof clean is one of the most basic, but also vital maintenance activities. Over time, leaves, dirt and debris collect on the surface which may lead to corrosion.

Clean the roof with low pressure wash or brush it using a soft-brittle brush. Avoid using the chemicals cleaners or abrasive utensils to keep the protective layer of the roof intact. 

Check for Rust and Corrosion

Metal roofing for commercial buildings are coated to prevent rust. But this protective coating can degrade with time or get compromised resulting in corrosion. One way to stop the decline is quick responsiveness.

Look for signs on the roof like discoloration, reddish-brown spots or flaking — all signs of moisture intrusion. If you spot any bare metal, seal it up immediately with suitable coatings or sealants. 

Inspect Fasteners and Screws

To protect metal panels, fasteners are crucial. With temperature changes, vibrations or high winds, they can loosen and jeopardize the roof’s stability.

Check for loose, missing or damaged screws and tighten or replace them as needed. Also, check the rubber washers to ensure they are intact and not worn down. When fasteners are secured properly they hold panels in place and keep them from leaking.

Examine Seams and Joints

The seams and joints are where the metal panels connect, and they could be susceptible to leaks if not properly preserved. These points require regular attention.

Inspect for gaps, cracks or separation in seams. Confirm if the sealant is worn out or dried. If done correctly, it forms an impenetrable barrier that keeps moisture from entering the building and stops lichen growth.

Maintain Flashing and Roof Penetrations

Flashing is used at the intersection of the roofs and other materials that can introduce water, including vents, skylights and HVAC units. These regions tend to be relatively common among the spots that develop leaks first.

Inspect flashing for rust, cracks or loose sections. Ensure that seals around penetrations are intact and not degraded. From there, prompt repairs avert water damage to the building’s interior.

Ensure Proper Drainage

It needs proper drainage to maintain your metal roof without trouble. First, never allow the breeding water to be stagnant because it will accelerate the process of inactivity of structure.

Clean your gutters and downspouts regularly by removing the debris to make sure water flows freely. Identify areas where water will pool and repair them promptly. Proper drainage will create the longevity of the rooftop.

Look for Physical Damage

Commercial roofs face foot traffic, equipment installation, bad weather and even pest damage. They can leave dents, scratches or other kinds of damage.

Check the roof for any clues (dents from hail, scratches that bare metal or punctures). Repair damages promptly to prevent further complications like leaks and rust.

Monitor Roof Coatings and Paint

Rust-inhibiting coatings and paint can reduce rust, too — and potentially improve energy savings through reflected sunlight. These coatings can wear away over time.

Watch for indications of wear, peeling or cracking. Fall back if required in order to remain protected. The coating makes your roof longer-lasting and more efficient.

Eliminate Hazards and Prune Surrounding Trees

If you have trees nearby, they can be a danger to your metal roof. Branches that fall, or continual contact with things also scratch the surface and can damage.

Trim branches overhanging the roof regularly and get debris off the roof. You have to keep the area clean, because it causes less damage and allows drainage.
